AMD X670 or AMD X670E
Prefer X670 as the better value unless guaranteed PCIe 5.0 graphics is a named requirement. X670E changes PCIe generation guarantees, not the platform's device count or tuning permissions.
The decision
Which one to buy
AMD X670
Choose X670 unless PCIe 5.0 graphics is a named requirement: device count and tuning are the same.
AMD X670E
Choose X670E for a guaranteed Gen5 graphics path and more Gen5 lanes.
Cheapest new X670 board at Newegg: $239.96. Cheapest new X670E board: $272.89, $32.93 more. Prices checked 31 October 2026, before tax and shipping.
The comparison
What differs
1 of 7 fields differ. Both sides of every row come from a published manufacturer document, cited on the row itself, with what the difference does once the parts are in a case.
| Field | AMD X670 | AMD X670E | What the difference does |
|---|---|---|---|
| Graphics link | PCIe 4.0 x16 or x8/x8amd.com | PCIe 5.0 x16 or x8/x8amd.com | Guaranteed Gen5 graphics is the concrete X670E distinction, and it is no practical difference for a build whose GPU is satisfied by Gen4 x16. |
What is identical: 6 of 7 fields
This comparison comes from published specifications, not from testing. We do not test hardware, and we never present a judgment as though we had. Current affiliate offers stay on category pages and do not determine this specification comparison.

The comparison in detail
The E suffix is narrow and honest. It guarantees a Gen5 graphics path and more Gen5 lanes, while CPU support, memory support, NVMe generation, total lanes, and chipset port ceilings stay aligned.
Prices: the two board lists above show every new board of each chipset at Newegg today, with its price. Two boards differ in more than their chipset, so compare the slots and ports you need before you read the gap as the chipset's price. Board makers list their models in catalogs such as Gigabyte's motherboard catalog (read 26 July 2026).
| Property | AMD X670 | AMD X670E | What it changes | Evidence |
|---|---|---|---|---|
| Platform support | AM5; Ryzen 7000, 8000, and 9000 support | AM5; Ryzen 7000, 8000, and 9000 support | X670 and X670E expose the same listed AM5 processor support, so the E suffix does not extend socket longevity. | X670, X670E, Updated 26 July 2026 |
| CPU overclocking | Enabled | Enabled | CPU overclocking permission is identical on X670 and X670E, leaving board power delivery as the model-specific consideration. | X670, X670E, Updated 26 July 2026 |
| Memory support | Dual-channel DDR5 with AMD EXPO memory overclocking | Dual-channel DDR5 with AMD EXPO memory overclocking | X670E provides no separate memory standard or EXPO tier, so compare DIMM support lists between actual motherboards. | X670, X670E, Updated 26 July 2026 |
| Graphics link | PCIe 4.0 x16 or x8/x8 | PCIe 5.0 x16 or x8/x8 | Guaranteed Gen5 graphics is the concrete X670E distinction, and it is no practical difference for a build whose GPU is satisfied by Gen4 x16. | X670, X670E, Updated 26 July 2026 |
| NVMe link | PCIe 5.0 x4 plus four general-purpose PCIe lanes | PCIe 5.0 x4 plus four general-purpose PCIe lanes | Both X670 versions specify the same processor-side Gen5 NVMe arrangement, so storage generation does not choose between them. | X670, X670E, Updated 26 July 2026 |
| Expansion I/O | 44 usable PCIe lanes total, up to 8 SATA ports, up to 2 USB 20Gbps and 12 USB 10Gbps | 44 usable PCIe lanes total, up to 8 SATA ports, up to 2 USB 20Gbps and 12 USB 10Gbps | Total lanes and chipset USB and SATA ceilings match, meaning X670E makes lanes faster rather than creating more connectors. | X670, X670E, Updated 26 July 2026 |
| USB4 | Optional | Optional | USB4 is optional for X670 and X670E alike, so only the motherboard specification can confirm its presence. | X670, X670E, Updated 26 July 2026 |
